KitchenAid Dishwasher F9E1: Long Drain Checks
THE SHORT ANSWER
The dishwasher is taking too long to drain.
F9E1 indicates a long-drain problem. Check accessible restrictions before assuming the drain pump needs replacement.
Look for a kinked visible drain hose and a dirty removable filter.
Disconnect power before maintenance; do not reach into a disposer or remove dishwasher panels.
WHAT YOU MAY NOTICE
